This invention relates to apparatus for removing the lower rolls of-thepresses of paper machinery, and more particularly to an apparatusprimarily intended for use in the which apparatus is of such characterthat it may be very readily installediand removed.

These and other objects I attainby the construction. shown in theaccompanying drawings wherein, for the purpose of illus-V, tration, Ihaveshowna preferred embodiment of my invention and wherein;

Fig. 1 is a side elevationof the lower portion of a primary press; V

Fig. 2 is a longitudinal sectional view through the press illustratingthe method of installing the removal apparatus;

Fig. 3 is an end elevation showing the re moval apparatus in position;and v Fig. 1 is a plan view of the dolly track frame.

In the construction of primary presses, the lower press roll 10. usuallyhas its bearings mounted upon a removable block designatedat 11 insertedbetween the frame 12and the roll bearings 13. These blocks are removablewhen the lower press roll is swung from the upper press roll 14 by meansof the usual. links fragmentarily shown and designated at 15. Theremovable blocks illustrated are those illustrated in a copendingapplication of Albert H. Stamlle'ay, Jacob Edge and Edward T. Street.filed July 18, 1932, Serial No. 623,278, for Primary press section, forpaper machines,'since the ordinary removable blocks do not affordsufficient space to enable convenient use of the apparatus now to bedescribed. Such space could, however, be 'afiorded with the ordinaryremovable block of the usual primary press construc- 1932. Serial No.623,279.

tion by simply making these blocks of slightly greater depth than'th'eyare now made.

Assuming the press roll 10 to have been supported and the blocks 11tohave been rei moved, I first provide an extremely light beam 16 ofgreater length than the distance between the frame elements 12, and ofsuch Weight that it may be'readily placed inpo sition by a solitaryworkman. This beam may be conveniently constructed of aluminum andpreferably is made in the standard structural I-beam form. This beam isplaced in position directly under the roll with its inner end restingupon the frame at that side remote from the side at which it is desiredto remove the roll. 21 track frame 17, more particularly shown in Fig.4c, is then installed in position: This track frame comprises spaced Ibeams 18,,the spacing of which is maintained through spacers 19 arrangedabove'the base ofthe frame a distance greater than the height'of beam16. This frame is of slightly greater length than the distance betweenthe press frame elements 12 and the spacer 19 at'the inner end of theframe has mounted thereon a flanged roller 20 of a diameter such thatthe bottom of frame 17 and the bottom of beam 16 are coplanar when theroller rests upon the I beam 16. Flanges 21 of this roller are spacedapart a distance such that they embrace the edges of the upper flange22of the I beam 16. This roller serves to support the inner end of theframe 1? as the frame is moved in position beneath the press roll 10 anduntil the ends of this frame are seated upon the press frame ele ments12.

A dolly 23 is provided, comprising a transverse beam 24 mounting at itsends rollers 25 having at their outer ends flanges 26 to engage theouter edges of the flanges 27 of the I beams 18, and an arcuate plate 28adapted to receive the roll and support the rear end thereof. It will beobvious that the forward end of the roll can then be placed in a slingand the roll thus supported may be shifted outwardly until slightly morethan one-half its length projects beyond the frame 12 at thatside of themachine from 1.7 0

Which the roll is being removed. At this time the end of the roll may besupported by the usual tripod and the sling shifted to engage the rollat the center thereof.

Since the construction hereinbefore set forth is obviously capable ofconsiderable modification Without in any manner departing from thespirit of the invention, 1 do not Wish to be understood as limitingmyself thereto except as hereinafter claimed.

I claim:

1. In press-roll-removing apparatus, a beam to seat on the press framein underlying relation to the roll to be removed, a frame includingtracks and having a support to engage the beam Whereby the track framemay be supported at its inner end as it is moved beneath the press roll,and a dolly having means to engage said tracks including means tosupport-an end of the press roll.

2. In press-roll-removing apparatus, a track'frame adapted to engage thepress frame and be supported thereby, means to temporarily support saidtrack frame during installation of the track frame and While the trackframe is moving longitudinally of the roll, andfa dolly having rollersto. engage the tracks of the track frame including means to support anend of the press roll.

3. In pressroll-renioving apparatus, a beam to seat on the press framein underlying relation to the roll to be removed, a frame includingtracks and having a support to engage the beam whereby the track framemay be supported at its inner end as it is moved beneath the press roll,and a dolly having means to engage said tracks including means tosupport an end of the press roll,.said frame comprising spacedstructural beams and spacers maintaining the spacing and assemblythereof, one of the spacers mounting a roller comprising said support.

l. In press-roll-removing apparatus, a beam to seat on the press framein underlying relation to the roll to be removed, a frame includingtracks and having a support to en the beam whereby the track frame maybe supported at its inner end as it is moved beneath the press roll, anda dolly having means to engage said tracks including means to support anend of the press roll, said frame comprising spaced structural beamshaving flanges forming said tracks.

5. In press-roll-removing apparatus, a beam to seat on the press framein underlying relation to the roll to be removed, a frame includingtracks and having a support to engage the beam whereby the track framemay be supported at its inner end as it is moved beneath the press roll,and a dolly having means to engage said tracks including means tosupport an end of the press roll, said frame comprising spacedstructural beams having flanges forming said tracks, the track-engagingmeans of the dolly comprising flanged rollers.

6. Press-roll-removing means comprising a dolly to en age the pressroll, a frame-in sertible in the press longitudinally of the press rolland of a length to seat on its ends on the press frame, a light beammanually supportable for insertion in the press to un-- derlie the roll,said frame and beam including co-acting means whereby the entering endof the frame is supported and guided during insertion of the frame inthe press.
